A black hairy tongue is caused by too much bacteria or yeast growth in the mouth: the bacteria build up on tiny rounded projections called papillae. These lie along the surface of the tongue. Instead of shedding as they normally do, the papillae start to grow and lengthen, creating hair-like projections.
This is because there can be many causes for a black appearing tongue. It doesnât necessarily have to be black, but can also appear yellow or brown. It can also be accompanied by bad odor or even have fuzz on it. People also complain of a bad or metal taste in their mouth.
